Bloody DPF's! Cleanable, removable or mega bill time?
Discussion
Hi all
I have a Mazda 6, with the 143 bhp Common Rail Diesel Engine. I've had it around 2 weeks, and I was well aware of the DPF issues. I chose the Mazda over others as I do permanent motorway mileage, 100 + a day, so I took a gamble on the DPF as a pose to dual mass flywheels/ injectors of the rival CR engined cars in budget.
So, sadly last week, my DPF light came on. As per my owners manual, I cogged it down to 4th and set the cruise north of 70, to get the revs up. The light went out 15 minutes later. Unfortunately it came on again on Friday. This time i was unable to do a high rev run, but it went out at next restart.
So, I'm led to believe that an illuminated light means it is trying to "regen" for the 4th time, after 3 consecutive failures. So, I gues what I'd like to figure out, is if a garage can clean the DPF, or force a regen somehow? Alternatively, will it be removable? (I presume this would need a remap at very least).
Cheers in advance for advice

You can do a forced regen on the DPF, using most generic diagnostic tools. Any half reasonable garage should have the kit to do it. I have heard of people removing the filter standing it on its end and filling it with brake cleaner ( or similar solvent then giving it a good going with a steam cleaner) but dont blame me if it goes tits up lol

You can force a DPF regeneration, your Mazda dealer should be able to carry this out.
If it's clogged and won't regenerate you can remove it and have the car mapped to eliminate the DPF from the software
Any specifics on how its done? Does anyone have a recommendation of a good place to get it done.If it's clogged and won't regenerate you can remove it and have the car mapped to eliminate the DPF from the software
I'm not worried about giving it death if necessary! My commute tomorrow is 48 miles m1. So, 4th gear at 3k rpm, or more drastic?
How does I know when its actually re generating? Massive amounts of smoke or something?
I've owned my 60,000 mile Alpina D3 from new (2007). Without warning I had the DPF warning light come on and stay that way. Car went into 'limp' mode. Tried various fuel additives without success. Took it a BMW dealer as well as an independent specialist, both of whom inspected it and said it was totally blocked and impossible to clean. Ended up costing me £1500 labour & materials for a replacement (wasn't covered by the warranty as it was deemed a wear and tear item). Apart from this, the car has been a joy. However, it'll certainly be the last diesel vehicle I buy.

If that's possible then a secondhand looks better, is it ok to drive with it removed?.If it's clogged and won't regenerate you can remove it and have the car mapped to eliminate the DPF from the software

I really doubt they are impossible to clean. Look on youtube at a product called 'seafoam'. Its not like your normal additive and causing a massive smoke screen. They are only about $10 in america but I dont know about import costs due to being a chemical? A guy on ebay sells them for about £20!
Im guy buy a couple and put them through a couple of my families cars and see the results.

I know someone who had the DPF light come on in a Mazda 5, all that was required was a oil change and then a DPF reset (not regen) via diagnostics
Alternatively there are people who can remove the DPF and then using specialists tools remove the DPF program from the ECU

I had this on my polo bluemotion used to come on every couple of hundred miles which vw said was normal used to just put it in 4th at 65 for a few miles until it goes off my current leon does it about every thousand I just do the same and it clears it but if it becomes as frequent as the polo was I'll be removing it for £400 from an ebay company if I were you I'd just do this.
ps. if you live in a city I would remove it anyway I took the polo to london for a weekend and it nearly killed it. It wouldn't boost, wanted to stall when pulling off at anything less then 2000rpm and absolutely drank fuel (relatively speaking) but then half hour on the motorway on the way home and it had fixed itself

Slightly concerning when they market them as city cars...ps. if you live in a city I would remove it anyway I took the polo to london for a weekend and it nearly killed it.

So if you have to drive the car at big revs for ages to regen....doesnt that negate the benefits of the thing in the first place ?
The DPF helps get the car through a set of EU emissions tests, what happens afterwards when it is on the road is irrelevant. What do you think it is for, saving the planet or something?
Check out this cleaner, its not your run of the mill crap, my bro used it on his BMW (after being told by a dealer that he required a new DPF) and it is right as rain...
